FRANK HENRY MARTIN, OF SAN FRANCISCO, CALIFORNIA.

SCALE-SCOOP.

To all whom '51 may concern:

Be it known that I, FRANK HENRY MAR- rm, a citizen of the United States,and a resident of San Francisco, in the county of San Francisco andState of Californimhave invented a new and Improved Scale-Scoop, ofwhich the following is a full, clear, and exact description.

My invention relates generally to scoops and more particularly to scalescoops where in the amount of material contained within the scoop may beindicated.

The object of my invention is to provide a scale scoop having meansthereon adapted to contain a quantity of material, other means beingprovided whereby when the scoop is held in vertical position, the massof material contained therein may be indicated.

A further object of my invention is to provide a scoop having a handlemovably connected thereto, the handle acting as a support for the scoop,there being a gage on the handle along which a member on the scoop ismovable to different positions de-' pending on the mass of materialwithin the scoop whereby the said mass may be weighed or indicated.

A further object of my invention is to provide a scale scoop made up ofa handle and a receptacle, the two parts being movably connectedtogether, there being suitable means for holding the receptacle rigidwith respect to the handle whereby a suit.- able quantity of materialmay be inserted into the receptacle, the said means being movable inorder to permit the receptacle to move relatively to the handle to weighthe said material and indicate the weight thereof.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is aperspective view of the scoop; Fig. 2 is a plan view thereof; Fig. 3 isa side view, the position of the parts when the scoop is indicating theamount of mate rial carried thereby being shown in dotted lines.

The device is made up of a receptacle .1 of any suitable form of crosssection or volume, together with a handle 2 having a bifurcated endportion comprising arms 3, 1,

each arm being provided at its outer end Specification of LettersPatent.

with a slot 5 engaging the pins 6, 7, carried at opposite sides of thereceptacle 1.

A rod 8 extends rearwardly from'thc back of the scoop and into thehandle 2, the end of the rod being in engagement with a hclical spring 9within the handle; adjacent the top of the receptacle 1 a number ofteeth or serrations 10 are provided which engage with similar teeth orserrations 11 at the outer end of a bell crank lever 12 which is pivotedat 13 to one end of the handle 2, the lever being provided with a thumbrest 1%, there being a suitable spring 15 engaging the thumb rest andthe handle.

Along either one of the arms 3, +1, a number of scale divisions 16 areprovided which indicate ounces or pounds or fractions thereof, therebeing an index 17 on the side of the scoop which is movable along eitherone of the arms and which indicates the mass of material within thereceptacle 1 by pointing to any one of the scale divisions.

Vhen the scoop is in use in obtaining a quantity of material within thereceptacle from a bin or barrel, movement of the receptacle relativelyto the handle 2 is prevented by reason of the engaging teeth 10, 11 onthe scoop and the bell crank 12. The zero mark on the scale 16 ispositioned so that when the scoop is held in an upright position and thereceptacle is empty, the index 17 will coincide with this Zerograduation. After a quantity of material has been inserted into thereceptacle 1, the mass of that material is indicated by movement of thereceptacle between the arms 3, 1, the pins 6, 7 moving in the grooves 5.The helical spring 9 is of such material and resiliency that it isexpanded more or less depending on the material contained within thereceptacle, the amount of the material being indicated by pressingdownwardly on the thumb rest 14:, thereby carrying the teeth 10, 11outof engagement. Of course the series of graduations 16 will depend onthe size of the scoop and the material which it is designed to handlealong with the volume of the receptacle 1, these graduations beingmarked thereon in advance so that the compression of the spring 9 isproportionate to the mass of the material in the receptacle. After thematerial has been weighed it is emptied from the receptacle, and due tothe expansion of the spring 9, the receptacle will come back to theposition shown in Fig. 1. By releasing pressure on the thumb rest, theteeth 10, 11 will again come into engagement and the scoop into positionto take out more material from the barrel or other source of supply. Thepins 6 and 7 are protected by means of a plate 18 rigidly mounted on thearms 3 and 4.

Of course the material of which the scoop is made may be anything suitedto the purpose and the size and shape of the parts may be determined bythe use to which the device is to be put, such modifications beingembraced within the spirit and scope of my invention as defined in theappended claim.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent A device of the class described comprising a handlehaving arms at one end thereof, grooves adjacent the outer ends of thesaid arms, a receptacle having pins at opposite sides thereof positionedbetween the arms, the said pins engaging in the said grooves, a seriesof graduations on' one of the arms, an index on the scoop and movablealong the graduations, a rod extending rearwardly of the scoop and intothe handle, a spring contained Within the handle and engaging the end ofthe said rod, a lever pivoted to the handle and having the thumb rest atone end thereof, the other end of the lever being provided With a numberof teeth, a number of teeth carried by the receptacle adapted to engagethe teeth on the lever, and a spring engaging the said thumb rest andthe handle whereby the said teeth may be held in engagement with eachother when the scoop is being filled, movement of the thumb restcarrying the teeth out of engagement whereby the mass of material withinthe receptacle may be engaged by the said index and graduations.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
